Inorganic lead and electrolyte (sulfuric acid) are the primary components of every battery manufactured by EnerSys.
Other ingredients may be present dependent upon battery type. Contact your EnerSys representative for additional information.III. PHYSICAL DATA
Boiling Point: 203 – 240° F Specific Gravity (H2O = 1): 1.215 to 1.350Melting Point: N/A Vapor Pressure (mm Hg): 10Solubility in Water: 100% Vapor Density (AIR = 1): Greater than 1Evaporation Rate: (Butyl Acetate = 1) Less than 1 % Volatile by Weight: N/A Appearance and Odor: Manufactured article; no apparent odor. Electrolyte is a clear liquid with a sharp, penetrating, pungent odor.
IV. FIRE AND EXPLOSION HAZARD DATA
Flash Point: N/A Flammable Limits: LEL = 4.1% (Hydrogen Gas) UEL = 74.2%Extiguishing Media: CO2; foam; dry chemical. Special Fire Fighting Procedures: If batteries are on charge, shut off power. Use positive pressure, self-contained breathing apparatus. Water applied to electrolyte generates
heat and causes it to spatter. Wear acid-resistant clothing. Unusual Fire and Explosion Hazards: Highly flammable hydrogen gas is generated during charging and operation of batteries. To avoid risk of fire or explosion, keep sparks or other sources of ignition away from batteries. Do not allow metallic materials to simultaneously contact negative and positive terminals of cells and batteries. Follow manufacturer’s instructions for installation and service.
V. REACTIVITY DATA
Stability: Stable Conditions to Avoid: Prolonged overcharge; sources of ignition Incompatibility: (Materials to avoid) Sulfuric Acid: Contact with combustibles and organic materials may cause fire and explosion. Also reacts violently with strong reducing agents, metals, sulfur trioxide gas, strong oxidizers and water. Contact with metals may produce toxic sulfur dioxide fumes and may release flammable hydrogen gas. Lead Compounds: Avoid contact with strong acids, bases, halides, halogenates, potassium nitrate, permanganate, peroxides, nascent hydrogen and reducing agents. Hazardous Decomposition Products: Sulfuric Acid: Sulfur trioxide, carbon monoxide, sulfuric acid mist, sulfur dioxide, and hydrogen. Lead Compounds: High temperatures likely to produce toxic metal fume, vapor, or dust; contact with strong acid or base or presence of nascent hydrogen may generate highly toxic arsine gas.
